Dundee United hope to hear within 48 hours whether Jason Scotland wins the first round of his appeal against the rejection of a new work permit.
Scotland scored five goals last season
The Trinidad and Tobago striker will have to leave the UK on Friday if his appeal fails.
Scotland, who made just 26 starts in two seasons with United, told The Sun: "I'm still in shock about it all.
"I still cannot understand why I was denied a permit as I was playing regularly for the club."
Scotland, who has played half his games for United as a substitute, has just returned from international duty in the Gold Cup in Miami, where he started all three of his country's matches.
Should the immigration department rules in the 26-year-old's favour, he will be allowed to remain in the country until his case his heard again by the football authorities.
United director Derek Robertson said: "The paperwork has been lodged and we are now hoping to hear back from Work Permit UK by the end of this week.
"Jason is back in Scotland, but he can't take part in any sort of training activities or any work with us, so he is waiting patiently at home for some news."
United chairman Eddie Thompson had taken the fight for a work permit to the House of Commons with the help of a United director who is also a member of the House of Lords and an MSP.
"I'm using Mike Watson to lobby local ministers down in the Commons," Thompson told BBC Sport.
A panel of former players ruled against the striker's permit application.
And Thompson slammed the decision to put Scotland's fate in the hands of five former Hibernian players and Scottish Premier League secretary Iain Blair.
"Iain Blair probably hasn't even played football in his life," Thompson claimed on BBC Scotland's 90 Minutes programme.
"And then the others had all played for one team and I found that a little strange.
"We will also be asking for the authorities to look into that."
The Home Office informed the club on Wednesday that the Trinidad and Tobago international's application for a renewed permit had been turned down.
But Thompson added: "Anybody that knows me knows that I am a very determined individual and we have put the strongest package imaginable to the lawyers and we expect to find out next week if we can have another review.
"I believe that we have put all the evidence together to get the ministers to have a rethink."
Scotland scored five goals for the club last season, including the one that took them to the Scottish Cup final.
